If a nozzle with a 65° spray angle is changed to a 110° spray angle, what must happen to the boom?

When the spray angle of a nozzle is increased from 65° to 110°, it results in a wider distribution of the spray pattern. To effectively cover the target area without causing excessive overlap or leaving areas untreated, the boom must be raised. By raising the boom, you improve the coverage uniformity because the wider spray pattern is distributed over a larger area.

Additionally, a higher boom height allows for more even coverage across the crop or field, reducing the risk of pesticide drift and enhancing application efficiency. The increase in spray width combined with the need for better coverage necessitates that the boom position be adjusted upwards to maintain proper application rates and effectiveness.
